ciao-scheduler: glog distinct messages for no cn/nn connected
ciao-scheduler: glog distinct messages for no cn/nn connected

Workload starts fail if no compute nodes are connected.  Same for network
workloads if no network nodes are connected.  This is different than if
nodes are connected, but don't have sufficient resources.  But it did not
show clearly in logs.  These two glog messages should add debugging of
cluster config/setup/test.
